FIELD OF THE INVENTION

The present invention relates to a data processing method and system that defines and utilizes a meta data model representing work products and deliverables, and more particularly to a meta data model that provides traceability of business requirements to implemented services.

BACKGROUND OF THE INVENTION

Conventional techniques for managing work products and deliverables focus on individual business requirements and the corresponding information technology (IT) that supports the business requirements without providing an overall business architecture context. Such conventional techniques result in inefficient duplicated services, thereby failing to facilitate reusability of service-oriented architecture (SOA) solutions. Furthermore, the known techniques for managing work products and deliverables are deficient in identifying valuable types of SOA solution capabilities. Thus, there exists a need to overcome at least one of the preceding deficiencies and limitations of the related art.

SUMMARY OF THE INVENTION

In first embodiments, the present invention provides a computer program product comprising a computer readable storage medium. A computer readable program code is stored in the computer readable storage medium. The computer readable program code contains instructions executable by a processor of a computer system to implement a method of tracing a business requirement to an implemented service in a systems development lifecycle by processing data conforming to a data model. The data model comprises:

a first asset type (functional requirement type) that represents a functional requirement;

a second asset type (process element type) that represents a process element;

a third asset type (business service type) that represents a business service;

a fourth asset type (standard type) that represents a standard;

a fifth asset type (service design type) that represents an information technology (IT) service design;

a sixth asset type (service component type) that represents a service component of the business service;

a first relationship between the functional requirement type and the process element type, wherein the first relationship specifies that the functional requirement is represented as the process element;

a second relationship between the process element type and the business service type, wherein the second relationship specifies that the process element identifies the business service;

a third relationship between the business service type and the standard type, wherein the third relationship specifies that the business service conforms to the standard;

a fourth relationship between the business service type and the service design type, wherein the fourth relationship specifies that the business service is designed as the IT service design;

a fifth relationship between the standard type and the service design type, wherein the fifth relationship specifies that the standard is a design template for the IT service design; and

a sixth relationship between the service design type and the service component type, wherein the sixth relationship specifies that the service design provides design guidelines for the service component,

wherein the service component realizes a service interface represented by a service interface type, wherein the service interface specifies the implemented service represented by a service implementation type,

wherein the functional requirement type, the process element type, the business service type, the service design type, the service component type, the first relationship, the second relationship, the fourth relationship, and the sixth relationship provide a tracing between the functional requirement and the implemented service, and

wherein the first asset type, the second asset type, the third asset type, the fourth asset type, the fifth asset type, and the sixth asset type are heterogeneous asset types.

In second embodiments, the present invention provides a computer-implemented method of managing a work product in a systems development lifecycle. The method comprises:

storing an instance of a data model in a computer readable storage medium; and

a computer system tracing a functional requirement to an implemented service, wherein the tracing includes:

-   -   displaying a first display of details of the functional         requirement, wherein the first display includes a first         hyperlink;     -   receiving a first selection of the first hyperlink subsequent to         displaying the first display;     -   responsive to receiving the first selection, displaying a second         display of details of a process element related to the         functional requirement by the data model, wherein the second         display includes a second hyperlink;     -   receiving a second selection of the second hyperlink subsequent         to displaying the second display;     -   responsive to receiving the second selection, displaying a third         display of details of a business service related to the process         element by the data model, wherein the third display includes a         third hyperlink;     -   receiving a third selection of the third hyperlink subsequent to         displaying the third display;     -   responsive to receiving the third selection, displaying a fourth         display of details of an information technology (IT) service         design related to the business service by the data model,         wherein the fourth display includes a fourth hyperlink;     -   receiving a fourth selection of the fourth hyperlink subsequent         to displaying the fourth display;     -   responsive to receiving the fourth selection, displaying a fifth         display of details of a service component of the business         service, wherein the service component is related to the IT         service design by the data model, and wherein a fifth hyperlink         is displayed via the fifth display;     -   receiving a fifth selection of the fifth hyperlink subsequent to         displaying the fifth display; and     -   responsive to receiving the fifth selection, displaying a         document of one or more documents that support the implemented         service,     -   wherein the first display, the second display, the third         display, the fourth display, and the fifth display are         heterogeneous displays, and     -   wherein the first hyperlink, the second hyperlink, the third         hyperlink, the fourth hyperlink, and the fifth hyperlink are         heterogeneous hyperlinks.

A process for supporting computing infrastructure corresponding to the above-summarized method is also described and claimed herein.

The present invention provides a program product and method for managing work products by utilizing a meta data model that provides traceability between requirements and implemented services. Relationships (e.g., dependencies) between work products are enforced by the meta data model so that any missing work products along the development lifecycle are easily identified. The meta data model also captures reuse of services by highlighting which consumers are calling on the service. Furthermore, the meta data model highlights the multiple capabilities that can be leveraged to fulfill an outcome.

In response to receiving the selections, the computer system presents a series of displays for viewing by the user. The series of displays presents a series of relationships between assets used in a systems development lifecycle, where the series of relationships presents a tracing between a business requirement and an implemented service for viewing by the user.

In a first tracing between a business requirement and an implemented service, the computer system presents a series of displays based on user-provided selections, where a first display in the series includes details of a functional requirement, a second display in the series includes details of a process element related to the functional requirement, a third display in the series includes details of a business service related to the process element, a fourth display in the series includes details of an IT service design related to the business service, and a fifth display in the series includes details of a service component related to the IT service design.

The service component realizes a service interface represented by a service interface asset type, and the service interface specifies an implemented service associated with the service component. Thus, the first tracing shows a relationship between the functional requirement in the first display and the implemented service associated with the service component in the fifth display.

In the aforementioned first tracing, the computer system generates the first display after the computer system accesses a stored functional requirement specified by the functional requirement asset type 204 (see FIG. 2). The computer system generates the second display after the computer system accesses a stored process element specified by the process element asset type 308 (see FIG. 3B).
